Setting up iSCSI on VMware ESXi 4.1 - Advice

Is it possible to setup ESXi 4.1 to use iSCSI storage? I've heard no, but when I go into VSphere, under configuration, storage, add storage, I see Disk/LUN or NFS. I've already added NFS volumes but I'm leary to by a iSCSI device if it won't work. Can anyone help me fill in the blanks?

Great news. 2nd question - this is our first iSCSI setup. I'm planning on using a PE 2650 and Openfiler as the data storage. As long as I'm on Gigabit everything, we shouldn't need any additional hardware, correct?

That's correct.
I'm assuming you're going to use the software iSCSI. To do this, click on one of your hosts. Click the configuration tab. Find the iSCSI Software Adapter in the Storage Adapters pane and click on it. Then click the properties button. Here is where you will first need to enable iSCSI and configure the initiator. You will need to configure the targets on the openfiler side too. Once everything is correct, a rescan of the iSCSI adapter will reveal the iSCSI storage under Disk/LUN. Thats it, in a nutshell.

Thanks paulsolov... I was just about to post that link.
dsmjeff - The software iSCSI adds more CPU overhead to the ESXi host(s). Having the hardware iSCSI HBA card offloads that CPU processing onto the HBA card. Otherwise, iSCSI performance is relatively the same.

Create a small volume for the OS on the Openfiler, leave the bulk unpartioned, otherwise you will not be able to use it for the iSCSI LUNs. BY default it may ask you to format the entire space for Openfiler OS
